WASHlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 316,064, dated April21, 1885.

Application filed November 27, 1883. (No model.)

To all whom it may concern.-

Be it known that we, MARTIN W. ROBIN- SON, of Somerville, in the countyof Middlesex and State of Massachusetts, and HENRY WV. MARRINER, ofBelfast, in the county of Waldo and State of Maine, citizens of theUnited States, have invented certain new and useful Improvements inWashing-Machines, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, makingpart of this specification, in which- Figure 1 is aperspective view of awashingmachine constructed in accordance with our" invention, the coverbeing removed from the tub. Fig. 2 is an elevation of one end of thesame. Fig. 3 is a transverse vertical section of the same. Fig. 4 isplan of the upper side of the dasher, and Fig. 5 is a plan of the underside of the same.

Our invention relates to that class of washing-machines having areciprocating dasher connected with an oscillating shaft, and has forits object to simplify the construction, reduce the cost of manufacture,and at the same time render the machine durable, efficient, and easy tooperate.

To this end our invention consists in a dasher supported within the tubor receptacle for the clothes by a frame connected with an oscillatingshaft by a single arm or hanger only, in combination with a spring orsprings so arranged as to allow the dasher to yield to accommodateclothes of varying thickness, and relieve the strain upon the workingparts of the machine; and our invention also consists in certain detailsof construction, as hereinafter set forth and specifically claimed.

In the said drawings, A represents the tub or receptacle for theclothes, water, &c., the interior of which is provided with longitudinalcorrugations a, forming a wash-board which is adapted to operate inconnectionwith the reciprocating dasher B, which consists of a board setedgewise toward the corrugated surface a, and inclined thereto, as shownin Fig. 3. The dasher B is supported by and slides upon a metal frame,0, Fig. 5, the ends I) of which fit within guides a, secured to theunder side of the dasher.

d d are screws which pass one through each guide a, between the two endsof the frame 0, serving as stops to limit the sliding movement of thedasher on its supportingframe in either direction.

The frameO is provided on its upper side with an arm or hanger, D, madeintegral there with, which projects up therefrom at an angle through anotch, e, in the. edge of the dasher toa horizontal rocker-shaft, G,which passes through its upper enlarged end, and to which it is heldimmovably by a set-screw, f, this shaft, which extends a little beyondthe center of the length of the tub A, being supported in suitable boxesor bearings in one end of the tub A, and in a bar or brace, H, extendingtransversely across the center of the same from side to side.

The sliding dasher B is forced toward the corrugated interior surface ofthe tub A by means of a stiff wire spring, I, of the form seen in Fig.4, the central portion of which passes around the hanger, D, and issecured thereto by a screw, g,while h, are attached to the dasher bymetal guides i, which form guides in which the ends of the spring slideas the dasher is moved backward and forward upon its frame 0.

By arranging the spring upon the upper side of the dasher, as shown, itis rendered easily accessible, so that it can be replaced by a new oneif broken without taking the machine to pieces, as has heretofore-beennecessary. We do not, however, confine ourselves to the use of a springof the precise construction shown, as a spring of other suitableconstruction may be employed, and, if desired, two or more springs maybe used instead of a single one only, as shown. The form of thesupporting-frame C may also be varied, if desired, and it may beconnected with the sliding dasher B by a guide or guides of any suitabledescription which will permit the free movement of the dasher upon theframe, and hold it securely in place thereon.

We will now describethe mannerin which the shaft G is oscillated toproduce the required reciprocation of the dasher 13 within its tub orreceptacle A.

To the outer end of the shaft G is secured a the opposite ends,

ICO

crank-arm, k, which is connected by a pitman Z, with a crank-pin, 'm, ona gear, 11, which turns on astud, 19, projecting from a metal plate, K,secured to the outer side of one end of the receptacle A. The gear at isdriven by a larger gear, L,which is mounted on astud, q, also projectingfrom the plate K, and is provided with a crank or handle, r, to enablethe machine to .be operated by hand. The gear t engages with a smallgear, 8, mounted on another stud, t, projecting from the plate K, andsecured to or cast in one piece with a fly-wheel, M, of suitablediameter, which also turns upon the stud t,- and thus through theconnections described, as the wheel L is rotated by means of the handler, the dasher B is rapidly oscillated within the tub A as required, andwhen the tub is supplied with water or a saponaeeous solution theclothes are caused to be thoroughly washed by the action of the dasherand the corrugated interior rubbing-surface a of the tub, the dasheryielding or sliding back on its frame 0 against the resistance of thespring I, to accommodate clothes ot'varying thickness, whereby it isprevented from becoming clogged or obstructed in case the clothes shouldbecome wedged or caught between it and the corrugated surface a, and allliability of their being torn or injured is thus entirely avoided.

The construction and arrangement of the outside gearing, whereby thefly-wheel is ro tated very rapidly, render it possible to employ a muchlighter fly-wheel than has heretofore been customary in machines of thisdeseription, the extra velocity producing an increased momentum, whichrenders the machine easy to operate, while the reduction in the size ofthe fly-wheel and in the length of the rocker-shaft G, and theemployment of a single hanger, D, only, greatly simplify the machine andrender it possible to construct it at a greatly reduced cost without inthe least impairing its efficiency. Furthermore,

by mounting all of the gears upon studs projecting from a single metalplate secured to the outside of the tub, they are prevented fromseparating and being thrown out of engagement by the shrinking andswelling of the wood, as is liable to occur when the shafts or supportsof the gears are separately secured to different portions of the woodforming the side of the tub.

Our-improved machine may be used either as a washing-machine or astarching-machine, as it is equally adapted either for washing clothesor for beating or forcing starch therein.

WVe claim- 1. In a washing-machine, the combination, with the tub A,having a corrugated rubbingsurface, a, and brace H, ofthe oscillatingand sliding dasher B, the single arm or hanger D, formed integral withits frame (J, the oscillating shaft G, carrying said hanger on its innerend, a spring connected with the dasher by guides, and gears foroscillating the shaft, all constructed to operate as herein set forth.

2. In a washing-machine, the combination, with the tub A, theoscillating hanger D, formed integral with its frame 0, and theslotteddasher B, sliding thereon toward and from the side of the tub, of thespring I, secured at or near the center of its length to the hanger Dand at its opposite ends within guides i a, secured to the dasher,whereby the ends of the spring are adapted to slide in the said guidesas the dasher is moved upon the frame 0, all constructed to operate asand for the purpose described.

Witness our hands this 23d day of Novemer, A. D. 1883.
